In Matthew chapter Two we read the story of several priests who come from the east to worship the new-born Christ. Who were these men? Where did they come from,and why did they come?
The Greek word used in the original translations is magos. The Greek magos itself is derived from Old Persian maguŝ who were the the religious caste of Zoroastrianism. So the term refers to the Persian priestly caste of Persian Iran. As part of their religion, these priests paid particular attention to the stars and gained an international reputation for astrology, which was at that time highly regarded as a science.
Their religious practices and use of astrology caused derivatives of the term Magi to be applied to the occult in general and led to the English term magic, although Zoroastrianism was in fact strongly opposed to sorcery.
Zoroastrianism encompassed the worship of a single deity called Mazda through the use of wisdom. It also encompassed versions of heaven and hell, free will and a messiah. It was the state religion of ancient Persia, and was wiped out by Islam. Some Zoroastrians remain today in India (think the Tata business group) and the Kurdis people.
With these facts in mind you can see how the priests of Iran could easily have been used by God to go on a journey west, following a star, and worshipping the newly arrived Messiah in Bethlehem.
